MP6526GU-Z

Overview

The MP6526GU-Z is a hex half-bridge motor driver manufactured by Monolithic Power Systems. It integrates six half-bridges with serial input control, designed for bipolar stepper and brushed DC motors. The device operates on a 4.75V to 5.25V supply voltage and supports load voltages from 7V to 28V. It delivers an output current of 1.3A per channel. The component is housed in a 24-QFN (5x5) package with exposed pad. It functions as a fully integrated driver with both control and power stages, featuring a serial interface for command input.

Feature Summary

• Integrates six half-bridge outputs for multi-phase motor control applications
• Utilizes serial communication interface for simplified system connectivity
• Combines logic control and power MOSFET stages in a single monolithic structure

Applications

• Bipolar stepper motor driving systems
• Brushed DC motor control circuits
• Automotive ignition controller modules

Procurement Notes

Verify the specific suffix 'GU' confirms the 24-QFN 5x5mm package variant distinct from other pinouts. Confirm RoHS3 compliance status through official manufacturer documentation prior to integration. Ensure design accounts for the specified thermal performance requirements associated with the exposed pad layout for adequate heat dissipation during operation.

Selection Notes

Select this part when a compact solution for driving multiple half-bridges via a serial interface is required. The 24-QFN package offers a small footprint suitable for space-constrained designs. Verify that the 1.3A output capability meets the load requirements and that the 7V to 28V load voltage range aligns with the motor specifications.

Part Context

This component belongs to the MP6526 family of motor drivers from Monolithic Power Systems. The family includes variants such as MP6526GY-Z which utilizes a 28-SOIC package. The GU suffix specifically denotes the QFN package configuration within this product line, maintaining identical electrical functionality while differing in physical form factor and pin arrangement.

Replacement Considerations

MP6526GR-Z is listed as a parameter equivalent substitute.
